The latest is that Ebay site Eclectic Mart who I bought the Head Unit from is sending the harness to my installer. They have provided me with excellent service and communication. They gave me a one year warranty on the unit themselves. They claim that they have never had a customer with this problem and they are a big Pioneer Dealer. Most of the time they say that the cable was damaged or crimped upon installation. I even sent them your post to read.
My installer says he is 99.9% sure it is not his installation. I hope it is because it is going to cost me another $100 clams to put in the new wire if it is not. If I had bought the HU from him then $0. But as you know, I got the best deal I could on EBay and I really shopped it. If there is a next time, you make sure that you have an Ipod and test everything before the dash gets put on.
I am going to watch them put it in and hope it is them.
Hey, thanks for your input.
